Zanaflex vs Flexeril – Which Is Better For Fibromyalgia?

Categorized as a chronic disorder, this condition creates magnified painful sensations throughout the human body by affecting the way the brain processes pain signals. However, some experts believe it to be a purely psychosomatic disorder – a product of the mind, while other doctors believe that this condition stems from genetic defects.

According to a June 2000 study, Zanaflex appears to be effective in reducing fatigue and pain, also reducing the number of painful tender points, and improving sleep and overall functioning in some people with fibromyalgia. The usual starting dose is 2 mg per day that can be increased to 4 mg per day after 5 days. The dose can be increased further as tolerated. Nevertheless, most sufferers remained at 4 mg or 8 mg per day, and the highest dosage used was 12 mg per day.

According to a 2011 double-blind study of 36 patients with this condition, fifty percent of the patients were given Flexeril (the initial dose was 1 mg and it was increased to 4 mg per day). The other patients received a placebo. After 2 months, people taking a placebo did not improve, but patients taking cyclobenzaprine experienced a positive difference with very few major side effects.

The main problem is that these drugs can cause side effects, mainly when used as a long-term treatment.
